Comparison of Corneal Nerve Regeneration and Sensitivity Between LASIK and Laser Epithelial Keratomileusis (LASEK)

The greater decrease in the number of subbasal nerve fibers in the LASIK group compared with the LASEK group may relate to the greater decrease in corneal sensitivity. The pattern of corneal nerve regeneration and the recovery of corneal sensation after LASEK did not differ greatly from that after photorefractive keratectomy in previous studies.
